Restrictor plate in BEGi exhaust
#41
Why is it that the same turbos on the engines they came on stock, like the sr20. The T25 turbine creep really seems to be a problem focused on mainly us and not so much on other cars. And its certainly not due to this motor being better than others. Are we like just better at tuning and running more spark advance than the other car?

And 3" exhausts?
My TD04 runs 5psi at red line and WOT, with the waste gate wired full open. And that must not be uncommon because Vlad told me it would. I don't know how it responds in a WRX.

I wonder if Corky will send me one of those?
I just wanted a ******* heat shield that fit or lacking that some stick on heat shield foil. In lieu of that I was offered a free A/O setup to make up for all the misery I went through with my S6 kit and it's boost creep issues.
Looks like the A/O is up for sale on the BEGi website. I haven't received the one I was promised, nor a phone call, nor an e-mail... not even a Christmas card.

BH2dKeith,
No A/O for you until the cast manifold is in my hands. The pattern has been at the foundry long enough to expect castings within a couple weeks.
Your turbo will need a few mods. You or me? If you do it, you will do it as I suggest.
I will be glad to fix it up, nc. What fuel system are you using? Need EGR?
Sorry about no Christmas card. It was just a bigger risk than I was willing to take.
Hang loose, you are at the top of the list. I'll need to figure out which list that was.

"an issue because of centripetal force on the compressor and turbine wheels"
Having seen turbine blade passing through the housing and hood, yeah, the cf is probably the top speed issue for a sleeve brg.
Otherwise, I doubt a sleeve bearing gives ****. However, the ball bearing guys might find the ***** spewed out into low earth orbit.
The centripetal acceleration of the wheels is reasonably high. For some impressive fun, calc the C A and then use that number to calc how long it would take to travel 283,000 miles.
